摘要
Abstract
The special module of system hardware watchdog is designed for the digital servo controller which uses the TMS320F2812 DSP chip as the core and the Domestic CPLD SM1032 （compatible with Lattice ispLSI 1032） made by State Microelectronic as the carrier. The watchdog has the function such as recognizing DSP reset timing, free to customize watchdog overflow timing. The design scheme and test results are acquired by analyzing, simulating and verifying the servo controller timing of power on and running.关键词
